The nonma gnetizable ring is, kor kflprevents magnetiomaterial from becoming deposited on the lowerfixedpoles Z), Z or 73 or entering the field gaps. As the Width. of thefield. gap of each of the magnetic fields is independent of the size ofthe particles, the height 01" the field gap can he smallso that a.strong magnetic field is produced With a relatively small consumption ofcurrent. .Gonsequently material to be treated in pieces of differentsizes ("for example from the finest grains up to say pieces of 5G mm.)can he treated simultaneously Without the neces sity of altering theWidth of the tield'gap. While the coarse pieces remhin in the magneticfield they are seized and carried by both poles of each field---direetlyby the upperpoletarmature ringiti) in the construction illustrated inFig, 1; by the lower pole (magnet 1)) through, the intermediary of Y thering is covering this pole; inrthe construction shown in Figs. 2 and 3,byboth poles through theintermediary of the ring 70 or 70 The positionof the feed device can.

either be selected in such'a manner that the path of the materialsupplied'crosse's the path of the separated magnetic material in anydirection or so that both paths run pan allel either. in the samedirection or in opposite directions.

. It should be noted that separators our bodying the invention areadapted both for wet and for dry treatment.

Having thus described my invention, what I claim as new therein anddesire to secure by Letters Patent is: i I

1. In a magnetic separator, a stationary magnet, a nonmagnetic guardentirely covering the active part of said 'magnct and. against whichguard the material is held by the magnet, said guard rotating to repoles are arranged i1ndlally in a common horizontal clans,

said first named magnetic oles; said more the adhering material whenlmyoud the action oi said magnet, a counter'nole adjacent iosaid magnetalso attracting the material, said counter pole also constructed torotate.

2. lo a magnetic separator, a stationary magnet, a nonhiagnet icguard.infront of said magnet against Which the material is held, by the magnet,means tor-rotating. said guard to remove the adhering-g material whenbeyond the action o'tsaid magnet, a ring shaped counter-pole ad3acent tosaid magn'et also attracting the material, and mg for said counter-pole,gearing actuated by said rotating means and con structcd to rotate saidcountenpoleatdilter- 'entspeed from that of said guard.

3. in a magnetic separator, stationary magnet, 21 counte.rpole adjacentmagnet, a guard against Which the material is held by said magnet and.said pole, said guard overlapping both the magnet and. counter-pole andmeans for rotating said. guard in order to remove the adhering materialWhenhe 0nd magnetic a, scar-- ing; for said C(P-JDiZQJf-PGltl c rootedto retate the counter-pole at a from said guard.
